Rich man's war. Poor man's fight.
And yes, it's tragic. It's all the more tragic because it destroyed our original constitutionally framed government and replaced it with one that claimed greatly expanded powers.
Thanks for saying that my ancestors were morons who had no idea what they were fighting for.
This is what they just can't handle. They want so desperately to believe in the revisionist fantasy of "dying to make men free" when it is clear from Lincoln's own statements as well as the statements of everybody from ordinary people at the time to the opinion shapers of the day and the politicians that freeing the slaves was the last thing they were fighting over. Some perfectly well understood they were fighting for money and empire. As always I suspect a lot of the average footsoldiers were sold the usual BS about nationalism and glorious adventure.
